Patent FR-2454340-A1 (FR)
IPC: F24C15/20
Filed: 1980-04-18
Abstract: The hood is intended to be mounted in the rear region between furniture walls (1) which project below the hood. The front region of the hood is provided with screening walls (5) so that here, too, the fumes to be extracted are trapped laterally. Each screening wall (5) is approximately rectangular and, in its downwardly pivoted effective position (5'), extends rearwards as far as the furniture wall (1) and forwards as far as the front hood lower edge. A knife-edge mount (6, 12, 13) with an open step bearing (12) and bearing knife-edge (13) serves for the pivotable mounting of the screening walls (5). The step bearing (12) is present at the screening walls (5) and a stationary stop (20) is allocated to the step bearing (12), which stationary stop (20), when the filter insert (18) is installed, cannot be overrun owing to contact (22) of the screening walls (5) at the filter insert (18). When the filter insert (18) is removed, the screening walls (5) can be moved out of the engagement region of the stop (20) so that the bearing knife-edge (13) passes out of the step bearing (12) and the screening walls (5) can be dismounted from the stationary hood part (4).

Title: Hand drill with penetration depth-indicating device - incorporates bearer foot on spring loaded sliding sleeve assembly
Inventor: SCHMUCK PETER
IPC: B25H1/00
Filed: 1980-06-20
Abstract: The hand drill (1) is fitted on its housing (2) with a rod-shaped penetration depth-indicating device (3) parallel to the drill bit (4). The device is mounted in a clamping assembly (5) and can be adjusted. The depth indicating device consists of a bearer foot (7) with bearer disc (7a) connected to a tube-shaped shaft (7b) of smaller dia. The bearer foot (7) is penetrated by tube-shaped holder (8) and the point of penetration forms a swivelling seat (9) for the bearer foot. Between the outer wall of the holder (8) and the inner wall of the shaft (7b) a ring-shaped gap is created. For fixing the holder in a required position a stop rod (3) is provided working together with the slidable clamping element (11) with a friction fit on the outer surface of the stop rod (3) operating against the pressure of spring (12) which compresses the clamping element with its end (12a) while its other end rests against the bearer foot (7).
Patent FR-2486048-A1 (FR)
Inventor: SCHEIDECKER GEORGES
IPC: B65H59/22
Filed: 1980-07-04
Abstract: In a thread or yarn brake for textile machines, the thread is guided between two spring blades, the braking effect of which is adjustable. The thread is fed by way of a thread entry guide and passes out of the brake by way of an eye. The spring blades touch one another only over a small part of their length. The exit eye can be offset laterally and axially in relation to the axis of symmetry of the spring blades. The brake is primarily suitable for irregular fancy threads or yarns.

Title: Non-destructive ultrasonic tube or rod testing - measuring end positions and suppressing undesired end signal
Inventor: STERNBERG WALTER
IPC: G01N29/38
Filed: 1980-07-25
Abstract: A non-destructive ultrasonic test method for pipes and rods involves passing the test piece through a measurement section and time-controlled evaluation of the start and end positions enabling suppression of disturbance signals from the rod or pipe ends. This enables reliable rapid testing including near the ends of the piece. Dimension measurement ultrasonic heads are used to detect the beginning and end of a test piece. The focal lengths of the fault detecting ultrasonic heads are selected to allow for suppression of the unwanted signals from the ends. The distances between the dimension measurement and fault testing heads and the focal lengths are automatically determined using a test specimen with known markings. The method is applicable to nuclear reactor combustion element casing pipe measurement and test.

Title: Speed adjuster for epicyclic gearbox - uses wheel in differential epicyclic gear train to position rack coupled to throttle linkage of engine
IPC: F16H3/44
Filed: 1980-08-01
Abstract: The device varies the speed of an internal combustion engine so that both input and output shafts in a gearbox are brought to the same speed before they are coupled together. The adjuster is partic. applicable to reducing losses in epicyclic gearboxes. A wheel (H) is incorporated in a differential epicyclic train so that it is stationary when the input and output wheels are at the same speed, and rotates in opposite senses depending on whether one wheel is faster or slower than the other. The edge of the wheel (H) has a worm cut to match to a rack (E) which is brought in contact with it by an electromagnet (G) energised when the transmission ratio is to be changed. The rack (E) moves the throttle linkage of the engine to adjust engine speed, bringing the gears to the same speed.
Patent FR-2464764-A1 (FR)
Title: Punching of blanks for mfr. of seamless tubes - indicating error of alignment by mercury bubble level
Inventor: ODENTHAL PETER
IPC: B21J9/04
Filed: 1980-09-12
Abstract: The first stage in making seamless tubes consists of punching a hole in the blank. If the punch is eccentric to the blank there is a deviation in the wall thickness of the finished tube. This defect can be avoided by fitting the punch (4) with mercury bubble levels (1). A number of electrical contacts (3) is sealed in the wall of the phial (1) containing the mercury. If the punch is not correctly aligned with the blank, the variation of the number of contacts (3) that are immersed in mercury generates a signal which indicates the error in alignment.

Title: Commande de groupe electrogene auxiliaire d'aeronef
Inventor: FAULKNER DENNIS T
IPC: F02C9/58
Filed: 1980-09-26
Abstract: Groupe électrogène auxiliaire de commande d'un générateur électrique et d'un compresseur d'air de pressurisation. Le groupe auxiliaire, destiné essentiellement à fonctionner lorsque l'aéronef est au sol, alors que les autres systèmes de production d'énergie sont à l'arrêt, peut toutefois être utilisé en groupe de secours pour produire un complément d'énergie alors que l'aéronef est en vol. Lorsque ce groupe est utilisé conjointement avec les générateurs principaux, l'admission d'air dans le compresseur de pressurisation 15 est réglée de manière à faire varier la charge que ce compresseur impose au groupe électrogène auxiliaire afin de minimiser les variations de vitesses de ce groupe et les fréquences transitoires électriques. Application essentiellement aux groupes électrogènes commandés par une turbine à gaz. (CF DESSIN DANS BOPI)

Title: Removable solar panel inner window shutter - has upper and lower thermostatic valves regulating air flow over panel
IPC: F24D5/00
Filed: 1980-10-22
Abstract: The solar panel shutter is fitted to the inside of the windows of buildings temporarily not in use. The panel consists of an absorber in an insulated frame. An inlet valve at the bottom of the panel and an outlet valve at the top are controlled by a thermostat situated behind the absorber. The valves can be controlled to allow air to circulate by natural convection over the panel when the solar radiation is above a certain level, closing off the circulation when the radiation is below that level. They may also be arranged to function independently to either heat incoming make-up air or to permit the extract of air from the building.

Title: Reclaiming heat from ore sintering belt - where gases collected by suction boxes in cooling zone of belt are recycled to ignition hood
Inventor: WALLET
IPC: F27B21/06
Filed: 1980-12-19
Abstract: A mixt. of ore and fuel is fed onto a sintering belt, and travels through a baking zone (A) equipped with suction boxes provided with a fan. Zone (A) is followed by a cooling zone (B), which is also equipped with suction boxes and a fan, which can drive the gases either to an exit chimney or to an ignition hood in zone (A), i.e. so the heat obtd. in zone (B) is reclaimed. Water is sprayed onto the baked material in zone (B); and the vol. of gas drawn out of both zones is virtually the same. The sintering conditions are adjusted so the agglomerate leaving the bed is sufficiently cool and contains no water; and all the gas collected in the suction boxes in zone (B) is recycled to the ignition hood. In addn. to reclaiming heat, the length of the cooling zone (B) can be reduced.
